Katter, who also served as the world governing body's finance director, was additionally fined CHF1 million (£830,000/$1 million/€950,000) by the adjudicatory chamber of FIFA's Ethics Committee.

The investigation into Kattner concerned amendments and extensions to contracts of FIFA employees, bonuses paid in relation to FIFA tournaments and the reimbursement of private legal costs.

It was launched in September 2016 and also investigated former FIFA President Sepp Blatter and ex-secretary general Jérôme Valcke for their roles in the illicit bonus and pay rise scheme.

German-Swiss Kattner had been sacked by FIFA in May of that year for "financial breaches", while Blatter and Valcke had already been banned from football when the investigation was launched.

Joining FIFA in 2003, Kattner was director of finance and administration from 2007 to 2015 and also deputy secretary general for the same period.

For a time from 2015 to 2016, Kattner was acting secretary general.

"The evidence appears to reveal a coordinated effort by three former top officials of FIFA to enrich themselves through annual salary increases, World Cup bonuses and other incentives totalling more than CHF79 million (£67 million/$83 million/€75 million) - in just the last five years", stated a law firm when releasing information on contracts and compensation given to a small group of FIFA officials which included Kattner.

FIFA's Ethics Committee found that the employment contracts of Kattner, Blatter and Valcke were amended to give them "extraordinary bonuses" in relation to the 2010 World Cup, 2014 World Cup and 2013 Confederations Cup.

Drafts of these amendments were found on a USB drive in Kattner's office. 

He also "failed to share the relevant information with the staff of the FIFA Finance and FIFA Human Resources divisions that he was the director of" in order to conceal the nature of these bonuses by not having them appear on relevant financial statements..

Kattner's bonuses in relation to the three tournaments totaled CHF7 million (£6 million/$7.5 million/€6.5 million) - Blatter and Valcke received more.

The investigatory chamber found Kattner in breach of three articles of the FIFA Code of Ethics - 15, in relation to loyalty, 19, in relation to conflicts of interest, and 25, in relation to an abuse of power.

The 10-year ban from all football-related activity matches the suspension given to Valcke, while ex-FIFA President Blatter is currently serving a six-year suspension.
